Are there any other uses for unique items other than transmuting them?

Ever since I discovered that you can transmute multiple unique items into a single unique item, I've been hoarding uniques. However, I've since come to the conclusion that transmuting uniques is a waste of time because my transmutes always result in an item that 1) isn't better than anything I already have or 2) can't be used by my character class. Therefore, I've decided that selling my lot of uniques is the best bet. Before I do that, though, I am wondering if they possibly serve any other purpose.
